a particular lanyard

[mikeref]

I have been looking for a particular type of lanyard for awhile. I have seen only a few refs with them and when I have had the opportunity to ask where they got it from they can't or won't help me.
The lanyard I am looking for is a noose style, but it is made of a heavier material than the standard so called NBA lanyard. The cord is thicker and the tightening mechanism is a larger circular devise with a push bootn center that allows you to tighten or loosen it. I really do not know how to describe this any better. Does this sound familiar to anyone? I have one type that is made from a plastic tubing with just a metal clasp as the adjusting part. I like this one but it is not the style that I am looking for.
Any and all help is greatly appreciated. Hope someone out there has a clue as to what lanyard I am describing and how to get one!
On another note, how do you feel about not using a lanyard? how many of you don't use one, and if you don't why don't you? Any advise for someone who wants to try not using one?
